Hi, I am a 48 y.o. male and I am considering getting a PKR. I have a OA fairly severe on the lateral side of my left knee. My question is will I still be able to enjoy outdoor activities (hiking, golf, occasional running/biking etc? I am told that these things are possible, but the activity can also seriously shorten the lifespan of the hardware. Has anyone received a PKR and still led an active lifestyle?
